int2bytes(i) = i2b(0) ' + by ' + bytes, i2b(0) ∈ int2bytes(i), 0 ≤ b2i(by), i ≤ 127, ∀ bytes, by, i0. i→n(i0) < i→n(i) → int2bytes(i0) = i2b(0) ' + by ' + bytes ∧ 0 ≤ b2i(by) ∧ i2b(0) ∈ int2bytes(i0) → false ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

name: int2bytes-byte rotate: F subst: [i] → [i]

Additional information

Used simplifier rules: ⊦ by ' = by0 ' + bytes ↔ by = by0 ∧ bytes = [];% ⊦ ¬ bytes + bytes0 ≠ [] ↔ bytes = [] ∧ bytes0 = [];% ⊦ by ' ≠ [];% ⊦ (bytes + bytes0) + bytes1 = bytes + bytes0 + bytes1; Used terms: i
